4.15.1 General

A 5GS can support time synchronization and TSC (see 3GPP TS 23.501 [8], 3GPP TS 23.502 [9], and 3GPP TS 23.503 [10]). This clause describes NAS-specific aspects of the 5GS features to support time synchronization and TSC. Interworking with EPS is not supported for a PDU session for time synchronization or TSC.
